TOOH-HOLDER FOR HORSE HAY-RAKES.

SPECIFICATION forming part of Letters Patent No. 269,492, dated December 19, 1882.

Application filed September 19. 1852.

To all whom it may concern:

Be it knowri that I, ELI M. \VHI'INEY, a citizen of the United States, residing at Hiusdale, in the county of Berkshire and State of Massachusetts, have invented certain new and useful improvements in Tooth-Holders for Horse Hay-Rakes; and I. do hereby declare that the following isa full, clear, and exact de scription of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a side eleva- Tion of a device in which my invention is embodied; Fig. 2, a face view thereof, and Fig. 3 a perspective view of the holder.

The presentinvention has relation to certain new and useful improvements in toothholders for horse-rakes, and refers especially to that class in which the rake-tooth is .held downward with a yielding pressure by a coiled spring, one end of which is free to rest upon the holder between the ears thereof, while the opposite end is fastened to a drum encircling a horizontal axis or bolt, to which the tooth is secured.

The object of the invention is to provide a device that will be simple in construction, strong and durable, and effective in holding each tooth independently of the others without danger of its working loose or the coiled spring becoming inoperative. hese several objects I attain by the construction substantially as shown in'the drawings and hereinafter described and claimed.

in the accompanying drawings, A represents the tooth-holder, secured to the axle or rake-head B by a suitable screw-bolt, a, and nut b. The holder A is cast with ears 0, between which is located a coiled spring, D, one of its ends, 0, resting in a groove, d, in the holder A, and held therein by the head of the bolt a, which secures the holder to the front side of the head or axle of the rake, thereby holding it firmly in place and preventing it from lateral displacement.

The toothrepresented at E may be of the usual form and of steel, and has its upper end bent at a right angle to the rest of the tooth, and in a direction toward the left-hand side of the rake. The bent end e passes through eyes (Model l VP f in the ears 0, and also through the coil of the spring D.

The holder A is cast with a shoulder, 9, upon which rests the upper portion of the raketooth, the end h of the spring D being bent in such manner as to embrace the rake-tooth and hold it down upon the shoulder. In addition to the shoulder g,'directly above it, the holder is cast with a recess, 6, and stop It, so as to allow the rake-tooth to be raised a short distance, but no farther.

The ear having the shoulder-recess and stop, as above described, is cast upon its inner side with a curved projection, l, broad enough to hold the first coil of the spring D from slipping out when taut. 7

It will be seen that a very simple, effective, and practical device is provided for-holding the rake-teeth each independent of the others, which is considered important in a rake for rough ground.

Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The combination, with a coiled spring having prolonged end 0 and hooked end It, and the rake-tooth E, having its upper end bent at a right angle therewith, of the holder A, cast .with ears 0, having eyes through which the bent end of the tooth passes to be encircled by the spring and grasped by the hooked end thereof, and formed with groove d and projection Z, substantially as and for the purpose set forth.

2. The holder A, having ears 0, grooved, and projection l, in combination'with the rake tooth E, having its upper end bent at a right angle therewith, and the coiled spring 1),

formed with hooked end It and prolonged end 0, the latter resting in the groove d and held therein by the bolt a, which connects the holder to the rake-head, substantially as and for the purpose specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

- ELI M. WHITNEY.
